Natural Selection is driven by a change in the environment and survival of the
Smartest
Fastest
Most well adapted
Biggest
Mutations are a change in what?
DNA
phenotype
genotype
What word describes a trait that helps an organism survive in its environment?
natural selection
mutation
camouflage
adaptation
What is most likely to happen to moth populations in the picture shown?
Light moths--hunted easily, dark moths--population increase
Dark moths--hunted easily, dark moths--population increase
Light moths--hunted easily, light moths--population increase
Lights moths will change their color to match dark moths.
TRUE or FALSE: Natural selection will still occur if individuals are exactly the same.
TRUE
FALSE

survive
go extinct
survive & reproduce

The more genetic variation a population has,
the more likely it is for some individuals to
evolve
migrate
survive
mutate
What is a way of hiding by looking the same as the background?
feature
distribution
chromosome
camouflage
An adaptive trait depends on the (fill in the blank)
environment
species
natural selection
predation
The presence of snakes creating an environment where high poison levels in newts becomes the adaptive trait is an example of a
prediction
effect
cause
distribution
What is a feature?
everything (living and nonliving) that surrounds an organism
an instruction for making a protein molecule
a change that happens because of an event
a characteristic that all members of a species have
Is being yellow always an adaptive trait in ostrilopes in a yellow environment?
Yes, it always is an adaptive trait because of camouflage
No, it never is because ostrilopes don't have adaptive traits
No, it only is when the ostrilopes have predators
Yes, it always is because carnithons can't see them
What does a histogram show?
Adaptive and non-adaptive traits
The distribution of traits within a population
The variation of features for a species
The variation of adaptive traits within a population
What is an instruction for making a protein molecule?
a mutation
a chromosome
a feature
a gene
What is a trait that makes it less likely that an individual will survive in a specific environment
A non-adaptive trait
A feature
A trait
An adaptive trait
What information can you gain from this histogram?
The population has high distribution
The population has low variation
The population has high variation
The population has no variation
What can you tell about this population of Thornpalms from the histogram?
High water storage is an adaptive trait
It has a non-adaptive trait
It has medium to high variation
It has low variation
What can you tell about this population of newts from the histogram
Most of the newts have high poison levels
Most of the newts have medium poison levels
Low poison level is the adaptive trait
You cannot tell anything about the poison levels
Where do the genes that determine an individual's traits come from?
An individual can be born with any genes, since genes are random.
Individuals grow genes specific to their environment.
Parents pass their genes down to their offspring.
Parents choose which genes their offspring have when each individual is born.
How can an individual be born with an adaptive trait?
The individual can choose to change to the adaptive trait when they want to.
The parents had genes for the adaptive trait, which they passed down to the individual.
The individual can choose to have the adaptive trait at birth.
The parents can choose for the offspring to have genes for the adaptive trait.
